Iodine Clock Reaction Investigation

Flashcards covering important vocabulary and concepts from the iodine clock reaction investigation.

Iodine clock reaction

A chemical reaction that produces iodine, which reacts with starch to produce a blue-black color.

Potassium iodide (KI)

A chemical compound used in the iodine clock reaction as a source of iodide ions.

Hydrogen peroxide (H2O2)

A reactant in the iodine clock reaction that provides an oxidizing agent.

Sulfuric acid (H2SO4)

A strong acid used in the iodine clock reaction as a catalyst.

Erlen Meyer flask

A laboratory container used to mix chemicals, typically used in titration and reactions.

Stir plate

A device used to mix solutions continuously during chemical reactions.

Initial rate

The rate of reaction measured from the moment reactants are combined until the first color change is observed.

Trial 1, Trial 2, Trial 3

Different experimental setups in the investigation where varying volumes of reactants are used to determine the rate of reaction.

Rate of reaction

The speed at which a chemical reaction occurs, measured by the time it takes for a color change to appear.

K constant

A value that indicates the reaction rate constant in relation to the concentrations of reactants.
